They're both cool pedals, but could do with something that's gonna layer up nicely. The sustain on that comp is fairly immesne though, is that just compression?! Bit ludicrous referring to it as the "most versitile compressor on the market" howeve. My FEA dual band which I thankfully managed to find second hand for about half the new price (never would have afforded one otherwise, if I ever got to the end of the massive waiting list that is), plenty of other comps with more functionality then that too. For the price and if you're after that sort of punchy transparent low mid heavy tone then it looks perfect though. That grit is nice too, shame they didn't show it at a few different levels as it was pretty full on in the video, could still hear some clean sparkel coming through though which was nice.
My thinking for the Pianet, was that I was gonna have some reverb on the go anyway to give a bit more sustain to the overall sound, then a dark sounding delay to make notes ring out when you wanted them to.
Whatever setting are used in the above video seem ideal for what I'm after, would just need momentary switching for it, which I know you can add to any pedal with a momentary footswitch soldered in. The reverb would hopefully cover the need for tails to stop it sounding too dead when it was released. I imagine it'll be a case of just getting the right settings - to make it seem as much like a continuous sound as possible, rather then an obvious delay - then getting the right brightness/darkness level to make it blend in as well as possible.
Not bothered about it sounding 100% organic, the Pianet very much sounds like an electric instrument anyway, just want a delay that can function in as similar way as possible to a sustain pedal! Unfortunately the actual sustain pedals don't allow layering with more sustained notes, just one sustaining sound to play over the top of with a dry sound.
